Abstract
A tunnel-plate type heat pipe is manufactured out of a tube having capillary parallel tunnels defined by partitions through shaping both ends of the tube, forming recesses in the partitions in the vicinity of each end of the tube, closing both ends of the tube to form a capillary tunnel container, cleaning the capillary tunnel container, and charging the capillary tunnel container with a predetermined amount of working fluid.
